| 摘 要： | 通过静态吸附试验，研究了ND－100超高交联树脂对水溶液中苯酚的吸附动力学和热力学特性，探讨了初始浓度对吸附过程的影响。结果表明 ND－100树脂对苯酚的吸附速率同时受液膜扩散和颗粒内扩散过程控制。吸附符合Langmuir和Freundlich等温吸附方程，吸附量随着温度的升高而降低，随着平衡浓度的增大而增大，吸附表现为放热的物理吸附过程。

| Abstract: | Study on adsorption kinetics and thermodynamics of phenol by NDA-100 hypercrosslinked adsorbent was carried out through static experiments. Effects of initial concentration and temperature on phenol sorption to resin from water were evaluated. The results show that both the external diffusion and the particle diffusion was the rate-controlling step. The adsorption date fit well into the Langmuir and Freundlich adsorption isotherm,based on the apparent enthalpy changes of adsorption, the uptake of phenols on NDA-100 hypercrosslinked polymeric adsorbent is a type of physical adsorption. |
